FIELD

The present teachings generally relate to one or more mobile platformswhich are adapted to receive and support one or more cartridgesinterchangeably, providing a convenient and efficient method oftransporting items.

BACKGROUND

The present teachings are predicated upon providing a convenient andeasy method of transporting items or materials from a first location toa desired location for any given task. The use of a cart to support andtransport items is well known in the prior art. The prior art has anabundance of various sizes and shapes of carts designed to transportspecific items or equipment for certain tasks. An example of a cart forindustrial vacuum cleaning is found in Marsolais, U.S. Pat. No.5,089,037, the teachings of which are expressly incorporated byreference herein in their entirety for all purposes. The design hasintegrated a vacuum, batteries, and a plurality of compartments directlyinto the cart to allow for mobile use of the vacuum for cleaning. InPresley-Mays, U.S. Pat. No. 6,520,513, there is disclosed a garden cartconsisting of a hollow frame, seat, umbrella, removable toolbox, andattachment points for a plurality of garden equipment.

Lenihan, U.S. Pat. No. 6,736,415, discloses a toy push cart frameincluding a base portion to support a plurality of interchangeable frameattachments. The interchangeable frame attachments include a basket,tool box, or a work bench. The work bench attachment includes aplurality of pull-out drawers for storage, a top work surface, and aplurality of recesses to receive one or more toy tools. Finally, Franco,U.S. Pat. No. 9,227,645 discloses modular customizable carts with aplurality of compartments allowing a user to connect two or more cartstogether for transportation.

Although these various prior art carts solve some of the shortcomings ofthe prior art, many provide solutions only for single problemsidentified for specific tasks. Therefore, it would be attractive to havea mobile cart for transporting one or more cartridges from one locationto a desired location. It would also be attractive to have one or morecartridges for organizing and transporting specific items for a plethoraof tasks. Additionally, it would be attractive to have the one or morecartridges be interchangeable between a plurality of mobile cartsranging in size and shape. What is needed is one or more mobile cartsthat can efficiently and conveniently transport one or more cartridges,while the one or more cartridges can organize different items forspecific tasks and be interchangeable between the one or more carts.
